UNIVERSAL'JOINT AND FLEXIBLE DRIVING CONNECTION.'

Specification of Letters Patent.

rammed May 9, 1916.

Application filed Apri120, 1915. Serial No. 22,546.

To all whom 'it may concern Be it known that l, Friaul-:moli li".Sajonia, a'citizen of the linited States, residing at Hollis Court, inthe county of Queens and State of New York, have invented new and usefulImprovements 'in Universal Joints and Flexible Driving loi'inections, ofwhich the following is a specification.

The object of the invention is to provide an improved universal jointand flexible driving connection, which is strong and eti fcc-tive forits purposes and cheap to manu facture.

The. preferred embodhm-nt of the invention will now be bricl'iylescribed, without specific reference to eqilivalent constructions whichwill suggest themselves to those skilled in the art, and the novelAfeatures will be more particularly pointed out in the appended claims. vn

ln the accompanying drawing: Figure l, is a fragmentary side view of thcentire flexible connection, with, intermediate porA tions broken away toreduce the length for purposes of illustration,` Fig. 2 is alongitudinal enlarged section on the line Q-Z of Fig. 1, with a portionbroken away and in terior parts shown in elevation; Fig. 3 is a .viewsimilar to Fig. 2, showing the joint iexed; Fig. 4; is a viewsimilar toFig. i2, the plane of the section being at right angles'to the plane ofthat viewg Fig. 5 is a cross-section on' the line of Fig. 2;

' Fig. (i 4'is a cross-section on the line 6--6 of Fig. 2; and Fig. 7 isa cross-section on the line 7 7 of Fig. 1.

The numerals 1 and 2 designate telescopic shaft members, connected. asto rotation by a spline 3, and constituting a shaft section which may belengthened or shortcned. It is mclosed by a casing consisting oftelescopic members 4t. and 5, the outer ends of which are connected tothe outer ends of the shaft sections l and 2 with rc spect to telescopicmovement but free as to rotation. In' this way, though the casing may berevolved with the telescopio shaft ,members as the result of friction,it is readily held stationary, thus removing any danger from exposure ofattendants or workmen to revolving slurf-ting. This is accomplished byforming tho outer portionsl of the shaft members with circumferential.grooves 6, in which screws 7 threaded through the walls of the casingsections are received' loosely. As indicated in Fig. 2,

spacing collars S may be interposed between the ends of the shaft andcasing members.

rlt the opposite ends of the telescopic shaft section are universaljoints, which are or may be of identical construction and only one ofwhich, therefore, need be described in detail. Each of said jointscomprises a pair of members 9 and 10, preferably in the form ofcylinders,- the outer ends of which are formed with sockets 11 toreceive drivingconnections. The ends of the shaft sections l and 2'carrying keys 12 enter the sockets ot' the cylinders 9, to Which theymay be clamped by .set screws 13. yThe sockets of the louter cylinders10, itWill be umlerstood, receive the elements of the transmission linebetweeen which the flexible and. extensible connection represented vbyFig. 1 is interposed..

formed with recesses or cuts, in the form of diametrical slots 14, andin these slots is placed loosely a fiat driving element or plate 15,thinner than the slots and having rounded ends 16, so that .the form ofthe recesses and intermediate element permit limited augnl ar movementof the cylinders in all directions, at the same time insuring adequateand annulus Work upon each other 'in the' manner represented in Fig. 3.

`What :is claimed as new is:

1. .d universal joint, comprising a pair of n'ienibers having recessesin their opposing ends, r. driving element occupying said reces. ,saidelement and recesses being formed to permitlimited flexing movement inall directions, and a universally jointed casing uniting` said membersand inclosing and 'retaining said driving element.

Q. A universal joint, comprising a pair of cylinders having registeringslots in their opposed ends, a plate thinner than said slots 75 Theopposed ends of the cylinders' are and' with rounded ends placedlooselythere# in, shells united to saidcylinders and having curved ianges, anda transversely'ciirved annulus receiving said flanges. n

3. In a universal joint, the combination of a pair of members havingrecessesin their opposed ends, an intermediate element loose in .saidrecesses, said .intermediate element and recesses being of such shapeand proportions .as to couple they said members for drivlng and topermit limited angular movei ment thereof in all "directions, shellsunited to said members and having curved flanges, and a transverselycurved annnliis receiving said ianges, said shells-and annulus connecty'universally yjointed easing nniting said cylinders andfretaining saiddriving element. Q

A flexible driving connection, c'omprlsshaft members havingcircumferential grooves adjacent said cylinders, telescopic casingmembers inclosing said shaft members, internal projections on vthe outerends of saidv casingl members entering said grooves, cylinders oppositethe aforesaid cylinders, eachL pair of 'cylinders having reing, incombination,y a pair of telescopicv i Vshaft members, cylinderssocketedto 'receive the remote ends 'of said shaft'inenibers, saidcesses in their opposed ends,.drving elements occupying saidrecesses,.andliexibly jointed casing members `uniting each pair yofcylinders.
